'nEcEr'rAoLE CLOSURE.

Application filed July 5, 1923. Serial No. 649,576.

My invention relates to receptacles and" closures therefor. An objectofthe inven tion is to provide an improved form of closure or cap, simplein construction, inex- 6 pensive to manufacture, which may be repeatedlyapplied to the container, and which is free from various defectsfound inclo sure devices at present in use.

It is also an object to provide highly effective yet simple retainingmeans for a closure or cap, said means including circumferentiallyspaced lugs stamped inward- 1y from the metal making up the cap and solocated that they present a maximum degree of resistance to yieldingunder pressure.

Other objects of the invention will appear hereinafter.

In the accompanying drawings: Figure 1 is a part sectional elevation ofa receptacle and closure constructed in accordance with the presentinvention, part of the receptacle being broken away.

Figure -2 is a top plan view ,of the closure or cap.

Figure 3 is a perspective view of the cap on a larger scale, parts beingbroken away.

Figure 4 is a part sectional plan of a portionof the cap. i

The closure or cap comprises a cover portion 6 and a skirt orflangeportion 7. The flange portion is formed with a circumferential rib 8 orapron which is preferably located a short distance above the lower edge9 of the flange and has an oblique top ortion. The lower portion of theskirt 7, Beneath oblique top of the rib 8, is bent inwardly and thenoutwardly to provide a flat annular surface 10 at the bottom of the cap.In other words, the lower portion is folded upon itself, the margin ofthe lower fold terminating at a point inwardly from the rib periphery toprevent contact with a users fingers. At intervals along the rib 8, themetal is bent inwardly to provide in-.

vides a tight seal when the cap is placed in position on the container.*By forming the rib 8 and the holdin ribs 11 from a portion of thematerial aiove the lower edge of the skirt 7 and separated from saidedge, the strength of said ribs is increased as compared with the usualconstructions in which the lower margin of the skirt is shaped to formmeans for holding the cap on the contamer. Moreover, with the presentconstruction, the lower side of the cap presents a smooth unbrokensurface '10.

Modifications may be resorted to within the splrit and scope of myinvention.

l/Vhat I claim is:

1. A sheet metal cap comprising a cover portion and a flange portionprojecting downwardly therefrom, said flange portion being bentoutwardly to form an annular rib, the bottom portion of the flange beinbent outwardly horizontally beneath sai rib closely adjacent thereto andparallel therewith to provide a smooth substantially flat annular doublefold surface at the bottom of said flange.

2. A sheet metal cap comprising a cover portion and a flange portionprojecting downwardly therefrom, said flangeportion being bent outwardlyto form an annular rib, the lower side of which is horizontallydisposed, the bottom portion of the flange. being bent outwardlyhorizontally beneath said rib to provide a smooth substantially fiatannular two-ply surface at the bottom of said flange, said rib havinportions thereof bent inwardto form holding lugs at. intervals alongsaid rib, said bent inward portions so shaped as to maintain the rib insubstantial continuity; I

3. A closure for a receptacle comprising a cover portion and a dependingskirt or flange portion, said flange portion being shaped to provide acircumferential rib, a strengthening horizontally disposed fold undersaid rib, and forming a substantial integral part of said rib, said ribbeing slitted at intervals, and sections of the rib between adjacentslits being bent inwardly to form holding ribs for attachment to areceptacle.

4. A closure .for a receptacle comprising a cover portion and adepending skirt or flange portion, said flange portion being shaped toprovide a circumferential rib, the lower side of whichis reenforced by afold of the margin of said flange upon itself, said vhorizontallydisposed annular reenforcing strip forming the bottom surface of thecap.

5. The combination of a receptacle having a neck portion provided withexternal spiral threads spaced at intervals around the neck,

and a cap forming a closure for said re-" ceptacle, said cap comprisinga cover portion and a flange portion, the latter provided with anannular rib intermediate the top and bottom of the flange portion, saidrib com-- prising portions projectin outwardly from the body of theflange an alternating with inbent holding portions, said holdingportions positioned to cooperate with said threads for holding the capon the receptacle, the portion of the flange beneath said rib being bentoutwardly at the lower edge of the rib to form a smooth unbroken bottomsurface for the cap.

6. A closure for a receptacle comprising a cover portion and a dependingflan e portion, said flange portion being shaped adjacent its lowerextremity to provide a circumferential apron horizontally disposed,

said apron consisting of an oblique top por-'-- tion, and a doublewalled horizontal flat lower portion, said apron being slitted atintervals to provide segregated portions, said portions being bentinwardly to form holding lugs for attachment to a receptacle.

7. A closure for a receptacle comprising a cover portion and a dependingflange portion, a part of said flange portion being shaped to provide acircumferential apron horizontally disposed, consisting of an obliquetop portion and a double folded horizontal flat lower portion, saidlower portion formed by bending the margin of said apron inwardlybeneath said oblique portion, and again bending the margin so as to bedisposed under said inwardl bent portion, thereby forming a double foled annular flat surface, and holding means formed in Said flat surfacefor attachment of said closure to a receptacle.

8. A closure for a receptacle comprising a cover portion and a dependingflange portion shaped adjacent its lower extremity to provide acircumferential apron, said apron comprising an oblique laterallyextending ortion folded inwardly at its outer edge to orm ahorizontalportion, and a ain folded back on itself, forming a two-pay flooring forsaid apron, and interrupted screw threads. formed fromsaid apron forengagement of said closure with a receptacle.
